Suppose That the Distribution of People's Ages in the United

Short Answer

Suppose that the distribution of people's ages in the United States is essentially constant, or uniform, from age 0 to age 60, and from there it decreases linearly until age 100.This distribution p(x)is shown below, where x is age in years, and p measures probability density.Such a probability distribution is called trapezoidal. According to this simplified model of the distribution of people's ages in the United States, what percentage of the population is between 0 and 100 years old?
